Generally anywhere you receive service you should tip. Tipping rates are vary from country to country so you knowing what to tip , where or how much to tip.
Tip in Restaurants and Cafes
According to general rule 12.5% of the total bill is considered a good tip in the service industry. In US and Canada, this tip rate is much lower than the 18-20% considered to be industry. Many restaurants in Europe are roughly a 12.5% ‘service charge’ to their bills and this is their way of making it easier for you to tip.
Tip in Bars and Clubs
In Some european countries have legal restrictions on the size of their pours so tipping more generally won’t get you stronger drinks either. Leaving any change less than a Euro or tipping 1 or 2€ per round would be considered a good tip for bar staff in Europe.
Tip in Taxis
Some Euros is considered a good tip for taxi drivers throughout Europe. Rounding up the fare, letting the driver keep the change or 2-5€ for longer journeys is sufficient.
